PCA9554CPWJ Description

Short technical summary and product information.

The NXP Semiconductors PCA9554CPWJ is a low-voltage, 8-bit General Purpose Input/Output (GPIO) expander. It is designed for I2C-bus and SMBus applications, offering a simple solution for systems requiring additional I/Os.

 

Key electrical specifications include an operating voltage range of 1.65 V to 5.5 V and a clock frequency of up to 400 kHz. The device supports both I2C and SMBus interfaces and features an interrupt output that signals changes in input states. The outputs have 25 mA sink capabilities, suitable for directly driving LEDs.

 

This I/O expander is housed in a 16-TSSOP package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The PCA9554CPWJ includes features like power-on reset (POR) and weak pull-up resistors on all input/output pins, minimizing the need for external components.
